Hi, I have two hubs, one I use for development and one for everyday (prod) use. It's still prettty anecdotal, but I am noticing lots of issues with pairing and operating particularly zigbee devices when both are on. Do you recommend having them run on different zigbee channels?
It can't hurt, is likely to help if anything (no matter how good Zigbee is supposed to be at "clear channel assessment"), and I don't see any reason not to if you don't have a reason (other Zigbee networks, devices picky about channel, concerns with other 2.4 GHz interference, etc.).
